Performance-based equity incentives, vesting restrictions, and corporate innovation

Purpose Based on the institutional background of mandatory requirement of performance-based executive equity incentives, this paper aims to investigate the impacts of executive equity incentives, vesting periods and vesting performance conditions on corporate innovation. Design/methodology/approach The empirical analysis is based on the detailed data of equity incentives in China's listed companies from 2006 to 2014, the Tobit method is implemented to estimate the regression coefficients, and the instrumental variable (IV) approach, Heckman two stage regression, propensity score matching and difference-in-difference models are adopted to solve the problem of endogeneity in several robust tests. Findings This paper documents that equity incentives and vesting periods are significantly and positively related to corporate innovation measured by R&D investment and patent applications, yet requirements on vesting performance impede corporate innovative activities. Specifically, compared with non-equity incentive companies, the R&D investment and the number of patent applications of equity incentive companies are 40 and 46.2 per cent higher, respectively. A one year increase in equity incentive duration can correspondingly increase the R&D investment by 15 per cent and the patent applications by 18.3 per cent. However, a one standard deviation increase in industry-adjusted ROE target reduces corporate R&D investment by 5 per cent and the patent applications by 8.39 per cent. The main empirical findings still hold after several robust tests.
